Embodiment Construction

[0040] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] In the first aspect, an embodiment of the present invention provides a part-time sensing method suitable for PUE in a V2P scenario, the method comprising:

[0042] Randomly select at least one sub-window as its sensing window in any PUE resource period; and obtain available time-frequency resources in the sensing window;

[0043] Taking at least one sub-window corresponding to the PUE resource period after the arbitrary PUE resource period as its selection window; and using the time-frequency resource to send service data within the selection window;

[0044] Put the PUE in a dormant state during the remaining time of each PUE resource period except the sensing win...

Abstract

The invention relates to a partial time sensing method and device suitable for a V2P scene PUE. The method comprises the following steps: randomly selecting at least one sub-window in any PUE resourceperiod as a sensing window of the PUE resource period; obtaining an available time-frequency resource in the sensing window; using at least one sub-window corresponding to the PUE resource period after any one PUE resource period as a selection window of the PUE resource period; sending service data by using the time-frequency resource in the selection window; and placing the PUE in a dormant state in the remaining time of each PUE resource period except the sensing window or the selection window, wherein the PUE resource period comprises a plurality of sub-windows obtained according to a preset partitioning method. The device is implemented based on the method described above. According to the method and device, the energy consumption of the PUE can be reduced as much as possible, and the working duration of the PUE is prolonged.

Description

technical field [0001] The technical field of intelligent transportation of the present invention, in particular, relates to a part-time sensing method and device suitable for PUE in a V2P scene. Background technique [0002] With the rapid development of modern automobile industry technology, the number of automobiles has increased rapidly, which has greatly improved people's travel environment. At the same time, it has also caused more and more traffic accidents and traffic jams, which in turn affects people's traffic safety. [0003] In order to solve the above problems, many manufacturers have begun to study information exchange technology between vehicles (V2V technology), vehicle-road information exchange technology (V2I technology), and vehicle-to-vehicle information exchange technology (V2X technology). And information interaction between vehicles and people can provide drivers with reliable traffic information, which can effectively improve the traffic environment. ...
